CPS: DFG Joint: Medium: Collaborative Research: Data-Driven Secure Holonic control and Optimization for the Networked CPS (aDaptioN)

The proposed decentralized/distributed control and optimization for the critical cyber-physical networked infrastructures (CPNI) will improve the robustness, security and resiliency of the electric distribution grid, which directly impacts the life of citizens and national economy. » More ...

Efficient UltRa Endpoint IoT-enabled Coordinated Architecture (EUREICA)

Task 1. Develop a web-based visual viewer & editor for the communications network configuration. The user should be able to select an existing configuration and the webpage visualizes it. The user can then add, update, and delete nodes and links. This includes configuration of applications on the selected node. Once editing finishes and the configuration is submitted, the configuration should be serialized and sent to the backend for processing. » More ...

Grid of the Future White Paper

This white paper will have a focus on operations, with much of it looking at issues in control center design for the wide variety of different entities that are involved in transmission system operation. These include reliability coordinators (RCs), balancing authorities (BAs) and transmission operators (TOPs). Issues considered will include the integration of large numbers of measurements from sensors (such as PMUs), operation with a much larger number of controls and renewable generation sources, and the need to maintain situation awareness during a wide variety of different operating conditions including during severe system disturbances. » More ...

HELICS+

WSU will build on the existing interfaces between transmission, distribution and communications. The steady state interface requires the interchange of data between the transmission and distribution power flow solutions in an iterative way to align the boundary bus voltages while taking into account the positive sequence model of the transmission interfacing with a three-phase model of the distribution. For the dynamic cosimulation, adding the interface with the communications system to that of transmission and distribution becomes important because many of the controls require the time behavior of communications to be taken into account. Moreover, the communications systems are not necessarily similar as the transmission and distribution SCADA systems are designed quite differently, and so does the data transfer of PMUs and AMI. » More ...

Nonlinear Analysis of Power System Oscillations using Models and Measurements

With the growth of renewable energy sources, the transmission flow patterns are changing in power grids all over the world. Moreover, fast dynamic devices that are built into the newer power electronic based energy interfaces and advanced control systems are interacting with the traditional power grid controls in unknown ways. These complex and nonlinear dynamic mechanisms are impacting on the small-signal and transient stability properties of the power system. This project will focus on the study of nonlinear phenomena in the presence of poorly damped oscillatory modes for understanding the impact of the nonlinearities on transient stability properties » More ...

Collaborative Research: Online Data Stream Fusion and Deep Learning for Virtual Meter in Smart Power Distribution Systems

We design a class of ad-hoc data fusion algorithms that can exploit and extract reliable values from heterogeneous measurement data streams. These algorithms retrieve and identify reliable true values in an ad- hoc manner whenever required, to ensure provable time cost and response time for real-time learning. (2) We devise a class of online stream learning algorithms to estimate virtual measures. These algorithms seamlessly integrate data-driven and physical models to fine-tune model parameters, and perform online model updates only when necessary, to ensure the feasibility over fast measurement data streams. (3) The proposed Virtual Meter closes the loop of interaction between data-driven methods and physics-based methods to provide enhanced estimation of real-time value of loads and states of power distribution systems. » More ...
